I am not sure of the answer but it is not a delta since a delta need not be marshy and the question asks about marshy land.
The mouth part of a river is called a delta. It is the large silty area at the mouth of a river at which the river spills into different slow flowing channels.

55 meters. This makes the length parallel to river 110 meters, total area = 55 x 110 =6050 sq meters. I did this using differential calculus. If you don't know this, you can try other combinations. Put short side equal to 50 or 60 meters and work out area, it will be less!
because your ears actually have a tube that reaches to your mouth. it is small but it still counts and can be felt. a cold is bacteria building up in your mouth and back of your throat area. the bacteria grows and can clog the tubes that go to your ears, hence the ear plugging.
a delta
Usually at the mouth of a river and is when the mouth spreads into a marshy area due to the deposit of sediment (thus, not every river has a delta). Well-known deltas include those of the Mississippi, Amazon, Nile, Ganges and Mekong.
The area of fertile soil at the mouth of a river is called river delta.
It is called a delta.
The broadened seaward end or extension of a river is known as the delta. It is in this area that the river will deposit excess mud on its way to the sea. Much of the delta is often very marshy and divided into many small waterways.
Nile Delta
The mouth part of a river is called a delta. It is the large silty area at the mouth of a river at which the river spills into different slow flowing channels.
Generally, the mouth of a river is found where it empties into another river, a lake, reservoir or ocean. A large river's mouth can cover a massive area.
